+Port settings are 115200 baud, 8n1, with 3.3V logic level.
+If you are using a Raspberry Pi, ensure that the serial port is activated first, many guides list these steps, here is a decent guide: https://www.engineersgarage.com/articles-raspberry-pi-serial-communication-uart-protocol-ttl-port-usb-serial-boards/
+Once wired up, and the serial port is enabled test that this works.  Confirm the system can use the port.

+  /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
+  /dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
+  /dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
+  /dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3
+It's likely /dev/ttyS0, use Linux's cli, 'cu'

+If done correctly, you will be presented with a login prompt, the login credentials for the web interface and this serial interface are the same.  Test that the system is wired properly before restarting.  Quite from cu with ~.  , that's a tilde, followed by a period.
